I've been looking for this item to protect my Dixon high pressure gauge and hope it fit.

Great transaction. The bike rack was about $90 less than a local retailer, and shipping was faster than promised. I wish all internet retailers were this reliable and useful.

Order arrived quickly and was exactly as described. Great prices and service!

Very fast shipping and price is rite
